- 对于CPVC材质阀体和过滤器过滤网装置，将破折号前面的字母“P”用字母“C”替代，并将字母“C”加在型号上，例如：BS22C8-020C
For CPVC body & strainer screen unit,
replace the letter "P" before the dash separator with
the letter "C" and add the letter "C" to the
part number (e.g., BS22C8-020C)
- 对于不锈钢过滤器过滤网，将破折号前面的字母“P”用字母“S”替代，例如：BS22S8-020；BS22S8-020C
For stainless steel strainer screens, replace
the letter "P" (or "C") before the dash separator
